Geordi claims that cargo bay 4 is on deck 4. Yet the big schematic display of the ship shows it on deck 10, and in "Power Play" when Worf, Troi and O'Brien head for cargo bay 4 they get off the turbolifts on deck 18.

Great Moment :

The holodeck scene where everybody tries to piece together what happened to them.

Body Count :

One.

Factoid :

For the alien scenes in this episode, actual dialogue was written and then transposed into clicks so that the pacing would sound right.
